Do not add '.product' suffix for product_specific module

When a module has both 'product_specific: true' and
'vendor_available: true', the module does not have core variant but
have product and vendor variant modules. As the module generated
multiple variants, the names of the modules have the variant name
suffix. However, it did not create the module with the base module
name because it does not have core variant.

As the base module, in this case, is the product variant, use the
base module name for the product variant without adding the
'.product' suffix to it.
